Definitions
- Circuits such as integrated circuits are oftentimes packaged in an epoxy mold compound packaging to support and protect the circuitry. Depending on the manufacturing method used, it may be difficult to control dimensions, shapes or certain properties of packaged circuits.
- US 2012/033017 A1 describes a liquid discharge recording head.
- US 2012/193779 A1 describes a semiconductor device.
- US 2003/036587 A1 describes rheology-controlled epoxy-based compositions.
- circuit package panel according to claim 1 and by a manufacturing method for a circuit package panel according to claim 9.
- Embodiments are defined in the respective dependent claims. Examples not comprising all the features of claims 1 or 9 are included as illustrative examples.
- Fig. 1 illustrates a diagram of a cross-section of a panel-shaped circuit package 1.
- the circuit package 1 has a panel shape in the sense that it has a thickness T between a back and front surface B, F, that is much less than its width W or length.
- its thickness T can be at least five times, or at least ten times its width W and/or length (in the drawing, the length extends into the page).
- the thickness extends in a Z-direction while the length and width W extend parallel to an X-Y plane.
- the circuit package 1 may be a component of, or an intermediate product for, a larger apparatus.
- the circuit package 1 includes a circuit device 3 packaged in a hybrid epoxy mold compound packaging 5.
- the packaging 5 includes at least two epoxy mold compounds 7, 9 that are each of different compositions. For example a filler density or filler diameter of each compound 7, 9 may be different.
- the circuit device 3 is provided near a front face F of the circuit package 1, opposite to a back face B.
- the packaging 5 includes at least one hybrid layer HL that includes both epoxy mold compounds 7, 9.
- the hybrid layer HL extends parallel to the front face F of the circuit package 1.
- the packaging consists of the hybrid layer HB but in other examples the hybrid layer HB may be provided between other layers that may consist of a single epoxy mold compound.
- the example epoxy mold compounds 7, 9 of different compositions that are patterned in a single plane X-Y.
- one of the compounds 7 is a bulk compound (i.e. that forms the bulk of the total volume of the packaging), while the other compound 9 may be patterned with respect to the bulk compound to control certain properties associated with the manufacture or use of the circuit device 1.
- the patterned second compound 9 has a different CTE (Coefficient of Thermal Expansion) than the first compound 7 of the same hybrid layer HL, to control warpage of the panel that would otherwise occur because of a higher CTE of the bulk epoxy mold compound with respect to the lower CTE of the circuit device 3.
- the circuit device 3 may be contain conductive and/or semi-conductor materials that generally have lower CTEs than bulk epoxy mold compounds. The difference in CTEs may generate deformations in the package during cooling. To counter deformations such as warpage, the CTE is altered. The CTE can be altered by varying the weight percentage of the fillers in the compound, also referred to as filler density.
- one of the compounds could have a different average filler diameter, filler length or different weight and/or volume percentages of added components like fillers or other components.
- a filler diameter can influence certain surface characteristics of laser ablated or cut panel parts.
- Fig. 2 illustrates an example of a circuit package 101 including a circuit device 103 packaged in a packaging 105.
- the packaging 105 includes a first epoxy mold compound 107 of a first composition and a second epoxy mold compound 109 of a second composition.
- the packaging 105 includes a first layer of a single epoxy mold compound 107.
- the packaging 105 includes a hybrid layer HL including both the first and second epoxy mold compounds 107, 109 in a single plane X-Y, over the first layer.
- the hybrid layer HL extends near a front face F. In the illustrated example the hybrid layer HL forms the front face F.
- the circuit device 103 extends in the first compound 107.
- the first compound 107 surrounds the circuit device 103 at the sides and back of the circuit device 103.
- the second compound 109 surrounds the first compound 107 within the hybrid layer HL.
- the second epoxy compound 109 extends along the sides and over the first compound 107.
- the first compound 107 may be a bulk compound of the packaging 105 and may extend under the second compound 109 and under the hybrid layer HL.
- the first compound 107 may form the back surface B of the circuit package 101.
- the circuit package can be manufactured through compression molding.
- Compression molding involves heating an epoxy mold compound disposed in a mold, depositing the circuit device and compressing the assembly of the compound and the circuit device, and cooling the circuit package 101.
- the thermal expansion of the circuit device 103 and the thermal expansion of the first epoxy mold compound 107 are different. Hence, warpage could occur during cooling, if the circuit device 103 would be packaged in a packaging of the first or second epoxy mold compound only.
- the back surface B could curve into a concave shape.
- the second epoxy mold compound 109 has a higher CTE than the first epoxy mold compound 107. In a further example the second epoxy mold compound 109 has a lower weight percentage of fillers than the first epoxy mold compound 107 to achieve the higher CTE.
- a hybrid layer HL that includes both the first and second epoxy mold compound is deposited adjacent to the circuit device 103 to increase an overall CTE of the entire hybrid layer HL. This may compensate for the difference in CTE with the back surface B and control overall panel warpage.
- the second epoxy mold compound 109 is disposed in a strategic quantity (e.g. thickness, surface) and location in the hybrid layer HL, near the front surface F.
- an overall thermal expansion of the hybrid layer HL during cooling may be similar as, or of inverse shape with respect to, the thermal expansion near the back surface B.
- the second epoxy mold compound 109 can be patterned around the circuit device 103 and around the first epoxy mold compound 107 so as to control the bow or warpage of the circuit package 1.
- certain design constraints can be relieved, such as circuit device thickness (versus length and width), number of circuit devices in a packaging, packaging thickness, mold temperature settings, substrate handling downstream of a compression mold such as an electrical redistribution layer (RDL) fabrication process, packaging clamping during cooling, and more.

- the weight percentage of filler in the first epoxy mold compound can be between 87 and 91%.
- the CTE of the first epoxy mold compound can be between approximately 6 and 9 ppm/C.
- the weight percentage of filler in the second epoxy mold compound can be between 82 and 87%.
- the CTE of the second epoxy mold compound is between 9 and 14 ppm/C.
- a different example of different CTEs of the first and second epoxy mold compound is 6 ppm/C and 13 ppm/C, respectively.
- An example of a CTE of a silicon of which a circuit device may be composed is approximately 3 ppm/C.
- Some of the examples of this disclosure describe placement of an extra epoxy mold compound of a different composition than a bulk epoxy mold compound, next to the circuit devices and the bulk epoxy compound, hence providing for a "patterning" effect in a hybrid layer of both compounds.
- Effects of such example circuit packages may include at least one of reducing bow, increasing design space, improving fluidic properties, improving electrical properties, and/or eliminating the need to add components or manufacturing process steps.
- the circuit package of the various examples described in this disclosure may be a subcomponent of a larger package or device, or an intermediate product of an end product.
- multiple other layers or components can be attached to the back or front surface.
- the back or front surface may not be visible or not apparent.
- circuit packages and manufacturing methods may relate to integrated circuit packaging for example for computer components.
- packages and methods may involve fluidic applications such as 2D or 3D printing, digital titration, other microfluidic devices, etc.
- the fluid may include liquids, inks, printing agents, pharmaceutical fluids, bio-fluids, etc.
- the example circuit packages can have any orientation: the descriptive terms “back” and “front” should be understood as relative to each other only.
- the example sheets or panels of this disclosure have a thickness in a Z-direction and a width and length along an X-Y plane. The thickness of the package may be relatively thin with respect to the width and length. In certain examples, the filler density varies over the thickness.
